The Luminosity Function of QSO Host Galaxies

We report on results from H band imaging observations of a complete sample of high-luminosity low-redshift QSOs. The luminosity function of QSO hosts is similar in shape to that of normal galaxies, although offset in normalisation by a factor of 10-4. This supports the hypothesis that the parent population of quasars is identical to the general population of early-type field galaxies.
